Simulate `bash` behaviour using Python and named pipes.

[Luca Cerone]

Thanks this works (if you add shell=True in Popen).
If I don't want to use shell = True, how can I redirect the stdout to named_pipe? Popen accepts an open file handle for stdout, which I can't open for writing because that blocks the process...
